For PowerFactory 2021 and earlier please refer to this example and attached files. For PowerFactory 2022 and onwards, this example is not supported anymore. Instead, a much easier alternative is…
The attached zip file includes a small project having a Python command predefined, which must be linked to the Python script included. The script will do the following tasks:- Prepare the initial…
The integration method is determined by the setting “Damping factor” in the "Calculation of Initial Conditions" command dialog, page "Solver Options", as follows: - “Damping factor” = 1: trapezoidal…
PowerFactory includes built-in devices to measure current (StaImea), voltage (StaVmea) and power (StaPqmea). Since PowerFactory version 2022, these devices calculate the instantaneous values, true RMS…
The AC voltage source can be controlled in RMS simulation by applying different input values to signal sets (u0,f0) or (U0,F0Hz). The first set controls the per unit quantities, the second absolute…

It is not possible to change the voltage set point of an external grid during a simulation. The work around is to replace the external grid by an AC voltage source (ElmVac) and then use one of the…
It is possible to represent photovoltaic (PV) systems in PowerFactory for the purpose of power system analysis. It is important to decide from the very beginning on the type of analyses being carried…
The attached project shows how events can be created based on the status of the breaker. Please note that this works only if the breaker is set to "detailed for calculation". Else the breaker may be…
Since version 2017 a new module for scanning the simulation is available. Attached an example how the Fault Ride Through simulation scan can be used. The project contains two study cases, in the first…
